Patent CA-2520217-C (CA)
Inventor: STEPHENSON CHRISTOPHER JOHN
IPC: E21B43/267
Filed: 2005-09-20
Granted: 2008-12-30
Abstract: A subterranean formation having natural fractures, which is to be subjected to hydraulic fracturing, is first pre-treated with an ultra lightweight (ULW) proppant having an average particle size between from about 12/20 to about 40/70. The small ULW proppant flows into the natural fractures and packs the fractures. The formation is then subjected to hydraulic fracturing. The pre-treatment serves to enhance the effective propped fracture length of the formation during the hydraulic fracturing by reducing the loss of fluid from the subsequently pumped fracturing fluid. The method is applicable to hydrocarbon bearing formations as well as non-hydrocarbon bearing formations and has particular applicability to coal beds.

Abstract: The present invention relates to a safety cartridge for a medical filter which can be inserted through a percutaneous access point, via a catheter or introducer, and placed in a blood vessel or other body passage. Filters may have features which are not longitudinally symmetrical, such as anchors or barbs which angle toward one end, or a retrieval hook at only one end. Depending on the physician's selection of the access point, the filter may be introduced to a desired site for treatment from opposing directions. However, it is desirable to introduce the filter with the desired alignment (inserting the desired end in first) regardless of where the selected access point is, and accordingly regardless of which direction of approach to the desired site. As a result, it is desirable to provide a safety cartridge. Cartridges hold filters in an initial compressed shape during storage and insertion into the patient. A safety cartridge may have labels and/or indicators corresponding to which approach direction is selected, showing which end of the cartridge, and so which end of the filter inside the cartridge, to insert first into a catheter or introducer. A safety cartridge may have uniquely shaped first and second ends, which match insertion port(s) on a catheter or introducer which correspond to the selected approach direction. Accordingly, the safety cartridge assists proper orientation of the filter during delivery and treatment.

Abstract: The present invention provides treatment methods involving modulating a sirtuin activity and/or a sirtuin mRNA and/or a sirtuin polypeptide level. In some embodiments, the present invention provides treatment methods involving modulating SIRT1 activity and/or SIRT mRNA and/or polypeptide level. The present invention provides methods of inhibiting SIRT1 Tat deacetylase activity. Methods of inhibiting SIRT1 Tat deacetylase activity are useful for treating immunodeficiency virus infections, particularly human immunodeficiency virus (HIV) infection. Thus, the present invention provides methods of treating an immunodeficiency virus infection, generally involving inhibiting SIRT1 Tat deacetylase activity. The present invention further provides methods of identifying agents that modulate sirtuin activity (e.g., SIRT1 activity), particularly ability of sirtuins to interact with (e.g., bind and/or deacetylate) a substrate, e.g., a viral substrate such as a Tat polypeptide. The present invention further provides active agents that modulate sirtuin activity or expression; and compositions, including pharmaceutical compositions, comprising the active agents.

Abstract: A graduated release valve for freight brake control is provided for a railcar having a pneumatic control valve, emergency and auxiliary reservoirs each normally charged with pressurized fluid from a brake pipe and a fluid pressure activated brake cylinder device for applying the brakes on the railcar. A selectively operable graduated release valve can include a metering valve and a changeover valve which selectively interposes the metering valve to exhaust brake cylinder pressure in a graduated manner responsive to brake pipe pressure. Alternatively, the changeover valve can isolate the metering valve and direct the pneumatic control valve to exhaust brake cylinder pressure in a conventional manner. The changeover valve can be operated responsive to the pressure in an air pipe supplied with pressurized fluid from a remote source. An auxiliary reservoir charging check valve interposed between the auxiliary reservoir and the brake pipe prevents the pneumatic control valve from going to release by connecting the brake pipe to the auxiliary reservoir.

Abstract: A method for pressure testing an engine to detect possible oil seal leaks. The engine is charged with a predetermined pressure while air pressure is also applied to an EGR valve intake port to offset leakage inherent in the EGR valve. Thereafter, a pressure drop in the engine pressure is used to determine whether an oil seal leak may be present. Applying pressurized air to the EGR valve intake port compensates for EGR valve leakage and prevents the EGR valve leakage from masking possible oil seal leaks, thereby making the system more sensitive to such potential oil seal leaks.
